(a) unpolarised light of intensity io is incident on a linear po- lariser sheet. light emerging from this sheet falls other sheet, which has its transmission axis at right angles to that of the first sheet. (i) what fraction of the incident light emerges from the second sheet? (ii) what happens to the rest of the light? (iii) leaving these two sheets untouched, and using two (2) additional linear polarisers, how could the system be modified so that the emergent intensity is increased? use a diagram to show the arrangement (iv) what is the maximum fraction of io that can now be transmitted through the system? you do not have to prove your answer is correct
